Portable Resistivity Logging System

- Nov 04, 2020-

Portable resistivity logging system is finished design and produce.

Resistivity logging is a method to measure the resistivity of rocks (including fluids) by using power supply electrodes and measuring electrodes arranged in different parts of the borehole. Resistivity logging includes ordinary resistivity logging and laterolog

The common resistivity logging is to put a common electrode system (composed of three electrodes) into the well to measure the variation curve of rock resistivity in the well. When measuring formation resistivity, it is affected by factors such as well diameter, mud resistivity, upper and lower surrounding rocks and electrode distance. The measured parameters are not equal to the true resistivity of the formation, but are called the apparent resistivity of the formation. Therefore, ordinary resistivity logging is also called apparent resistivity logging.
